Modeling and Simulation of Hose-Paradrogue Aerial Refueling Systems

摘要

A dynamic modeling and simulation analysis of hose-paradrogue aerial refueling systems is presented. A set ofngoverning equations of motion is derived using a finite-segment approach that describes the dynamics of the hoseparadroguenassembly under a prescribed motion of the tanker. The hose is modeled by a series of ball-and-socketconnectednrigid links subject to gravitational and aerodynamic loads that account for the effects of tanker wake,nsteady wind, and atmospheric turbulence. Numerical simulations show a good correlation of the model’s steady-statencharacteristics with previously reported flight-test data. Also investigated are the dynamic characteristics of thenparadrogue assembly resulting from atmospheric turbulence and a typical pitch doublet maneuver of the tanker.nFinally, the dynamic motion resulting from an in-flight adjustment of the paradrogue drag associated with strutanglenchanges is studied.
